Agreed. And looking at my other dyno run, it appears that the drop is at 7400'ish rpms.

I spent the weekend at Watkins Glen and the flash did not have any hiccups and I enjoyed the smoothness and the slightly better low end and mid range torque. And while my lap times dropped from the last time I was here, the top speeds on the back straight did not go up. I tried new lines and was definitely pushing the car like never before with higher slip angles and earlier on throttle out of turns and I think the smooth and linear throttle response from the AA tune played a small part in that

Here is one of my better recorded laps - Harry's Laptimer on TomTom GPS cradle and connected via WiFi to Elm CAN WLAN II for rpm signal. It was recorded at 720p on a iPhone 4S (my channel is http://www.youtube.com/mistralvr6).



Got home a couple of hours ago and reflashed the car with the updated file from AA. Will report back with changes and review.
